ration of Georgia meant-s August 18, l'i, seal N6; 1591770 5 Clainis.(01. 139-92) My invention, rf tes to" heddllba'r frames, and moreparticul" to that t pe of frame which h'as a siib'st I, al' lengthrelative to its height,v such as used in the weaving of wide fabrics. vI In relatively long heddle frames, it has been the custom, and n tact ae ee,ss1ty tqp vide the" heddle bars with one or more supports, intermediate of th ir' an Su ports, soas to prevent undue sagging ortwisting of th heddle bars due to theiweighti of thih'eddles and thevibration occasioned by the' movement of the heddle frame when inoperation. A

Frior' practice of supporting relatively long heddle bars intermediateof their ends, has included many forms of heddle bar supports or books.These known devices present many difficulties, owing to theirunsatisfactory operation;

multiplicity of parts which inherently involve probabilities ofmalfunction; and the cost of production thereof.

The present invention seeks to obviate the deficiencies of the knownhooks or supports and contemplates the provision of a hook, one end ofwhich is attached to the horizontal members of the heddle frame atspaced intervals and the other end of which is adapted to engage theheddle bars and maintain them in proper position, provision being madefor a ready release of the heddle bar from the hook by a movement of thebar in a plane substantially at right angles to the direction of itslength, whereby as a result of such movement the hook will be opened.The hook as herein disclosed does not require any manual opening of thehook per se to releasethe heddle bar.

Specific details of the present invention hereinafter appear, and willbe more readily understood from the accompanying description, taken inconnection with the accompanying drawing wherein:

v The heddle frame per se, usually constitutes the horizontal upper andlower members I' 2 respectively, generally fashioned from wood, andendmemberslfahdlfi connecting the u per X and lower members} specificconstruction in by which the top and bottom members and end members areconnected is well known in the art andvform's' no1part; of the presentinvention.

The hook illustrated in Figures 2, 3 and 4; consists" of a stationaryelement Sand a movit able element 6. The stationary element has one, endfashioned into' a' screw-threaded shank T and its opposite end formedinto'a hook portion rr ng d to provi th lo The mo a le .v element a hasone end connected to the Sta {5 tionary element by the pivot pin I I.The opposite end of the element 6 terminates in a hook portion l2arranged to provide the slot l3.

The inward surface of the movable element 6 in the region of the pin His provided with a cam surface M, the formation and inclination of whichis such that when the heddle bar I5 is moved toward the pivot and liftedclear of the slots l0 and I3, the edge of the heddle bar remote from theslot will begin to engage the cam surface It. Continued movement of theheddle bar toward the pivot and in engagement with the cam I4 will causethe movable element 6 to swing to open position, as shown in Figure 3,whereupon the heddle bar is released.

The inner surface of the stationary element 5 may be provided with a camsurface Ma, as shown in Figure 2a, the formation and inclination ofwhich is such that when the heddle bar is moved toward the pivot in themanner just described, the cam surface will move the heddle barlaterally, thus forcing the movable element 6 to open. Either or bothelements may be provided with the cam surface heretofore described, theaction of opening the hook being the same in r all cases.

The above construction is equally adaptable to heddle frames which carrymore than one heddle bar, as will be apparent from the followingdescription. As shown in Figures 5 and 6, a sta- 5Q tionary element I6is provided with a screw threaded shank I! for engagement with ahorizontal member of the heddle frame. The opposite end of thestationary element terminates in the multiple hook portions l8 and 20arranged to provide the slots 2| and 22. The intermediate portion of theelement 1 l6 may be enlarged so as to provide a suitable bearing for thepivot pin 23 and the formation of cam surfaces hereinafter referred to.

Movable elements 24 and 25 have one end pivotally mounted on the pin 23and the opposite end formed into the hook portions 26 and 21 arranged toprovide the slots 28 and 30 which receive the heddle bar. Cam surfaces3| and 32 are formed on the inner surface of each hook element and thesesurfaces function in the same manner as described in connection withFigure 3. Similarly the stationary element may have its opposite edgesformed with cam surfaces in the same man-,

ner as the element 5 illustrated in Figure 2a.

What is claimed is: 1. In combination with a heddle frame and heddlebars carried thereby, a hook carried by the frame and adapted to engagesaid bars comprising an element having one end attached to said frameand its opposite end provided with a slot for receiving a heddle bar, acomplementary element pivotally connected to-said first named elementprovided with a slot for receiving a beddle bar, and means associatedwith said elements and engageable with the heddle bar for opening saidelements upon a movement of the heddle bar in the plane of the slots andbeyond the point v where said bar clears said slots.

2. In combination with a heddle frame and heddle bars carried thereby, ahook carried by the frame and adapted to engage said heddle barscomprising an element having one end at- 35 tached to said frame and itsopposite end provided with a slot for receiving a heddle bar, a complementary element pivotally associated with said first named elementprovided with a, slot for receiving a heddle bar when the slot of saidlast a named element is in alignment with the slot of the first namedelement, and a cam formed on one of said elements for opening thecomplementary element upon a movement of the heddle bar beyond the pointWhere said bar clears said slots.

3. A heddle bar hook comprising a plurality of elements relativelymovable to open and closed position provided at one end with slots forreceiving a heddle bar when in "closed position, and means associatedwith at least one of said elements and engageable with the heddle barfor moving said elements relatively to open position upon movement ofthe heddle bar in the plane of the slots and beyond the point where saidbar clears said slots.

4. A heddle bar hook comprising a stationary element, a complementaryelement pivoted to said sationary element movable to open and closedposition, said elements being provided at one end with slots forreceiving a heddle bar when in closed position, a cam formed on thecomplementary element so fashioned and arranged that upon a movement ofthe heddle bar beyond a point where said bar clears said slot, thecomplementary element will be moved to open position.

5. A heddle bar hook comprising a stationary element, a plurality ofcomplementary elements connected to said stationary element and movableto open and closed position, all of said elements being provided at oneend with slots for receiving a heddle bar when in closed position, andmeans associated with at least two of said elementsand engageable withthe heddle bar for moving said elements relatively to open'position upona movement of the heddle bars in the plane of the slots and beyond apoint where said bars clear said :zlnf-S.
